Native VLAN (! no trunking here!) numbers are transported in CDP, and the warning also comes from the CDP process. DTP has nothing to do with it, and "switchport nonegotiate" won't change this in any way. The interesting thing about this error is that: > > Nov 30 14:54:27 192.168.0.113 26469: %CDP-4-NATIVE_VLAN_MISMATCH: Native > > VLAN mismatch discovered on FastEthernet0/15 (0), with SW1 > > FastEthernet0/18 (1). ... the switch that's printing this message is claiming that it's own port is in VLAN 0 (!), not in VLAN 1. Usually, these messages look like this: Nov 24 23:49:29 sw18-XXX: %CDP-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch discovered on FastEthernet0/4 (69), with sw34-xxx GigabitEthernet0/22 (1). which means "vlan 69 on my fa0/4 is not the same as vlan 1 on sw34-xx:g0/22". The original poster's switch has a "(0)" in the field for "local VLAN", and that's definitely weird.
